vrl`his invention relates to rope or wire grippers and more particularlyto a gripper of the hand tool' type in which the rope or wirev is heldby friction due to the direct contact between it and, the gripping facesof the tool. lVhile the tool is particularly adapted for use in slidingdown rope fire escapes other uses to which itlinay be put will appearobvious from the followingdescription. An object of' this invention istoprovide a tool of the above type in which the grip-l ping surfaces areprovided with rope posi tioning means for properly placing the ropebetween the surfaces of the tool and for'preventing displacement of therope therefrom. A further object is to provide a4 tool of the typedescribed struction, easy and positive in operation and cheap tomanufacture.

These and other objects, which will appear v obvious from the followingdescription, are accomplished by means of this invention, one which isshown in the accom Y panying drawings in which Figure 1 islaV frontelevation of a tool constructed inac-` cordance with this inventionshowing the same in operative relation to a iope, Fig. 2 is a sideelevation of the same, Fig. 3 is a vertical section on the line 3 8 ofFig. 2

, Vand Fig. 4 is a top plan view of the tool.

This invention is illustrated as being applied to a hand tool having twolever arms 1 and 2 which are pivotally connected by a bolt 3 similarly.to a pair of shears. The levers 1 and 2 are respectively provided withlaterally extending parallel arms 4 and 5 which are preferably formedintegral with the levers so as to provide a rugged construction.

The arms 4 and 5 have adjacent faces 6 and 7, respectively, which formrope gripping surfaces and av rope upon manipulation of the levers 1 and2 b y the handles 8 andv9 with which the levers are respectivelyprovided at their ends opposite to the rope gripping arms. In order toproperly position the rope between the gripping arms and also to preventdisplacement of the rope therefrom I provide inwardly extending fingers10 and 11 on the arm 4 and similar fingers 12 and 13 on the which willbe rugged in conf which are adapted to grip arm 5, between which therope is accommodated. In order to permit the arms 4y and 5"' i toclosely approach each other so as Jco-,grip l 'I a comparatively smallrope I provide grooves 14 and 15 in the arm for receiving the fingers 12and 13 on the arm 5. Thevlatter arm has similarv grooves 16 and 17 forreceiving the fingers 10 and 11 formed on the` arm 4. l The ropepositioning fingers not only prevent dis 67ov l' placement'of the ropefrom between the gripping arms 4 and 5 but also position the rope asufficient distance away from the handles 8 and 9Vto prevent yits cominginto contact with the hand Vof the manipulator with the resultantinjuryA or burning due to friction. l i 'y In sliding down a rope fireescape the levers are oscillated so as to spread thearms 4 and 5sucien'tly far apart to permit the in`ui sertion of the 1 ropetherebetween `and also withinv the inner fingers 12 and 13. By

gripping-the handles S and 9 the arms are caused to grip the rope withsufficient fric-- tion to enahleithe manipulator to slide down insafety. The lingers 10 and 12 prevent the ropefro'm' slippingout frombetween the gripping arms and the fingers 11 and 13 pre-V vent theropefrom approaching close enough to the handle of the toolto injure thehand of the operator.

llfhile I have ping arms on said levers, means for oscillaty ing saidlevers so as to cause said arms to grip al rope orkthe like, cooperatingstaggered fingers on said arms for positioning the rope therebetween.and grooves in each of said arms for accommodating the fingers on theother of said arms.v
